TVVBPG Shielded Elevator Control Cable

The TVVBPG shielded elevator control cable (traveling cable) is engineered to maximize operational efficiency and service life in modern lift systems. It delivers stable electrical control over long suspension lengths while reliably withstanding mechanical stress. As a shielded development of the established SKF504/805 design – equivalent to our SKF/80500 series, which adds a shielding layer to the SKF/80100 series – the TVVBPG is available with three selectable shielding constructions to address different interference environments.

Shielding Configurations for EMI Protection

Shielding options are listed in order of increasing cost:

• High-frequency interference – aluminum Mylar tape wrap shield

• Electromagnetic interference (EMI) – tinned copper wire braid shield

• Broad-band interference – aluminum Mylar tape plus tinned copper wire braid composite shield

Cable Construction

• Conductor – multi-strand ultra-fine bare oxygen-free copper wire, compliant with VDE 0295 Class 5

• Insulation – special-formulation PVC compound

• Core identification

  • Colour coding (GB 5023.6): yellow, white, orange, light green, pink

  • Number coding: black insulation with white printed numbers, compliant with EN 50214
    Please specify if a green/yellow earth core is required.

• Inner sheath – none

• Shield – yes (configuration selectable as above)

• Strength member (optional) – high-strength galvanized steel wire; high-strength galvanized aircraft-grade steel wire

• Video transmission element (optional) – high-strength military-grade copper-clad steel conductor, low-interference specialty coaxial cable for CCTV

• Outer sheath – cold-resistant PVC compound; grey (RAL 7001) or black (RAL 9005)

When to Integrate a Supporting Element

For flat-type elevator cables (conductors arranged in a parallel row)
When the free hanging length exceeds 35 m and the travel speed exceeds 1.6 m/s, a supporting element should be incorporated.

For cables with a bundled circular construction (cores laid up in a helical/star formation)
When the free hanging length exceeds 80 m and the travel speed falls between 4.0 m/s and 10.0 m/s, a supporting element must be considered.

The typical supporting element is a galvanized flexible steel wire rope or a synthetic fiber rope such as aramid yarn. Our engineering team will help specify the correct configuration for your hoistway layout and duty cycle.

4. FAQ

What is the TVVBPG cable and where is it used?
TVVBPG is a shielded flexible elevator traveling cable designed for control, monitoring, and signal transmission in traction and hydraulic lifts. The “P” denotes the shielded variant, providing enhanced protection against electrical noise that can disrupt sensitive control circuits.

What types of shielding are available, and how do I choose?
You can choose an aluminum Mylar tape wrap for high-frequency interference, a tinned copper wire braid for standard electromagnetic interference, or a composite tape-plus-braid shield for broad-band interference. Selection is typically based on the electromagnetic environment inside the hoistway and the required signal integrity. Cost increases from tape to composite.

When is a steel support member mandatory in an elevator traveling cable?
A steel wire or aramid support element is strongly recommended when the free hanging length and travel speed exceed certain thresholds: above 35 m / 1.6 m/s for flat cables, and above 80 m / 4.0 m/s for bundled round cables. These criteria ensure the cable can support its own weight and dynamic loads without conductor breakage.

Can I integrate a coaxial video line for lift car CCTV?
Yes. The cable can be manufactured with a high-strength copper-clad steel conductor low-interference coaxial element for reliable video transmission. Please state this requirement when requesting a quotation.

Do you offer custom core counts, colours, or jacket materials?
Absolutely. As a manufacturer, we provide full customization: core count, identification method (colour or numbering), jacket colour (grey or black standard), and cold-resistant PVC formulations to match regional standards and project specifications.

How can I get a sample or a project-specific quotation?
Contact our technical sales team with your required cable length, number of cores, shielding type, support member preference, and any optional video or data elements. We will return a detailed data sheet and competitive offer within one working day.
